The Missed Call That Almost Cost Me My HVAC Business - And the Tool That Finally Saved My Sanity

The Missed Call That Almost Cost Me My HVAC Business - And the Tool That Finally Saved My Sanity

Oct 10, 2025 - Mike Harlan

I Almost Lost a $5,000 Job Because I Couldn’t Pick Up the Phone.

It’s the kind of thing every small-shop owner dreads.

Last summer, during one of the hottest weeks of the year, I was on a rooftop fixing a busted compressor when my phone started blowing up in my pocket.

I ignored it - both hands deep in the unit, sweat pouring down, 98° heat.

By the time I climbed down and checked, there were three missed calls from the same number.

I called back. Straight to voicemail.

Next day, I learned that call was from a property manager needing emergency service for eight rental units. He hired another crew. That one missed call cost me nearly five grand in work.

That night I sat at my kitchen table staring at my phone, thinking:

“How many of these calls am I missing without even realizing it?”

I Was Doing Everything Right… Except the Phones.

I tried everything.

  • I paid a call center - they kept mangling customers’ names and quoting wrong prices.

  • I told my wife to help answer calls - she lasted a week before begging me to stop.

  • I even forwarded calls to my cell while on jobs - impossible to juggle while covered in dust or fiberglass.

No matter what, I’d still come home to voicemails from new customers who’d already found someone else.

Then I Found Something That Actually Worked.

Then I Found Something That Actually Worked.

A buddy in one of my HVAC Facebook groups mentioned he’d started using a new AI call-answering app that sounded like a real receptionist.

He said it answered 24/7, booked jobs, and even texted him summaries after each call.

I thought this is not going to work.

But a week later he sent me a screenshot: “Booked 3 new installs while on vacation.”

So I gave it a try.

It’s Called OttoCalls, and It’s the Closest Thing to Having a Full-Time Receptionist - Without Paying One.

The setup took me less than 10 minutes.

I just forwarded my business line to the App, and now every call gets answered instantly - even when I’m on a ladder or asleep.

This thing greets customers politely, asks what they need, and sends me a full text summary after each call:

“AC not cooling - needs service today. Appointment requested for 10 a.m. Tuesday.”

It even handles tire-kickers or after-hours calls without me lifting a finger.

Since Then, I Haven’t Missed a Single Lead.

In the first month alone, Otto booked 9 extra jobs I would’ve never caught.

That’s over $6,000 in revenue from calls I used to miss. But honestly, the money isn’t even the best part.

It’s the peace of mind.

  • I don’t race to answer calls during dinner.

  • I don’t lose sleep worrying about after-hours emergencies.

  • And my customers think I hired someone full-time.

You Guys Know This Feeling.

You Guys Know This Feeling.

You’re covered in sweat, on the road, halfway through a job, and the phone rings again.

You think, “I’ll call back in 10 minutes.”

Then the next thing you know, that customer’s gone.

OttoCalls fixed that for me - permanently.
